| titleOfInvention | Preparation of piperidine |
| abstract | PURPOSE: To obtain piperidine in high yield under mild conditions, by feeding furfurylamine, etc. to the liquid phase of a reactor kept at a given temperature, catalytically hydrogenating the furfurylamine, etc., and taking the reaction product together with excess H 2 gas in the vapor phase rapidly out of the reactor. n CONSTITUTION: Furfurylamine or tetrahydrofurfurylamine or both are fed to the liquid phase, containing a suspended catalyst, e.g. Raney cobalt, in a solvent, e.g. liquid paraffin, and kept at substantially a given temperature of a reactor, and catalytically hydrogenated at 100W400°C under ordinary pressure W200atm at an H 2 flow velocity to give 1:1W10,000 molar ratio between the raw material amine and the H 2 to take the reaction product together with the excess H 2 gas into the vapor phase of the reactor and give the aimed piperidine. Polycondensation products formed as a by-product by the reaction may be partially or wholly used as a reaction solvent. n EFFECT: Successive reaction of the piperidine can be suppressed. n COPYRIGHT: (C)1985,JPO&Japio |
